I'm getting lost at step 2 - Set up your back end server. I have set up a Heroku account just like it says and I go through the set up tutorial on the Heroku site. It all seems fine. I save the code listed in step 2 in a new file I created called opengraphobject.php (I have no idea if this was the right thing to do?).

After that it says "Once you've uploaded the dynamic object creation code, test a sample object using the Object Debugger. Enter a URL into the debugger, for example:"

Of course that makes sense. Should I replace the fb_sample_scrumps:meal with mynamespace:myaction? I tried pasting it into the object debugger with and without and it's giving me several warnings saying a description and title should be provided. Any idea what I might be doing wrong?

@Tiddly yes you need to replace it with your data, if it gives you warnings it means your dynamic php file (opengraphobject.php) isn't working properly.

Weird, my text editor was doing something funky that was adding a bunch of random characters to the file when I save it as a php file. I've switched editors and now it's saved correctly (is identical to the code int he FB tutorial). I'm still hitting the same issue when I paste the url into the object debugger tho :(
